Many vendors offer alternatives to mice in Apple's iMac and blue G3 systems. But the folks at Wacom Technology (800/922-6613,

) have a new variation on the concept: a $100 USB graphics tablet that includes a cordless, pressure-sensitive pen along with a cordless mouse with a scrolling finger wheel. The Graphire system, scheduled to ship in October, includes an 8-by-8-inch tablet with a 4-by-5-inch active area. The tablet is not compatible with Wacom's Intuos system and lacks such Intuos features as Tool ID and dual tracking.
